For many years, Apple's best kept secret was AppleScript. An incredibly powerful feature of Mac OS that was, when it was marketed at all, marketed by stealth. But now the mantel of "best kept secret" has been passed and the focus of Apple's stealth marketing activities has shifted to a new product.

WebObjects! Yes, that's right. The current focus of Apple's stealth marketing activities is WebObjects, a web application server for Windows NT, Solaris, HP/UX, and Mac OS X Server.

Originally developed by NeXT in the early 90s and based on many of the same technologies that underlay Apple's Mac OS X and Cocoa, WebObjects is the oldest and most mature application server on the market. Before there was Netscape Application Server, Visual InterDev, SilverStream, HAHTsite, or Tango, there was WebObjects.

Now on version 4.5, WebObjects' maturity shows in the cleanliness and quality of its architecture, as well as in the performance, scalability, and reliability it delivers.

When building web-based applications responsiveness and performance are critical. As Jakob Nielsen reminds us again and again in his AlertBox web columns (see Links of Interest below for the URL), the longer that people have to wait for a page to be delivered, the greater the chance that they will "bail out" and you will lose a customer.

As Nielsen's is fond of observing in his writings, in most non-Web settings, if someone has waited more than 10 seconds without a response, they will bail out and go somewhere else. Unfortunately, web users are use to quite a bit of abuse in the form of unresponsive systems, and they will usually wait 15 seconds before bailing out.

What does this mean for you? Well, on the negative side, it means that for the best user interaction and acceptance you need to get your page up there in 10 seconds or less. On the positive side, the faster you get your page displayed, the more you will stand out from the crowd. And as many sites have learned, strong and positive word of mouth often trumps millions misspent on stupid SuperBowl ads.

On the performance front, WebObjects wins heads down. In a study benchmarking the performance of a number of commercial application servers - including Netscape Application Server, HAHTsite, Silverstream, Visual InterDev, PowerJ Enterprise, Tango, and, of course, WebObjects - conducted by the research firm TechMetrix Research, WebObjects beat the competition across the board.

Pretty much across the board, WebObjects beat its nearest competitors by a factor of 4, and always delivered - even under the heaviest loads - the sub-10 second responsiveness that customers demand.

But don't believe me; check out the data for yourself. Go to the TechMetrix Research web site and check out the Application Server Performance Results for 1 to 10 simultaneous users and for 25 to 250 simultaneous users (see Links of Interest below for the URLs).

Hand-in-hand with performance, scalability is of equal importance to the success of any mission critical web site. If your system can't easily scale from 100 hits an hour to 10 million hits an hour, then you are setting yourself up for a whole lot of hurting in the future.

First, as the TechMetrix performance benchmarks we discussed above show, WebObjects nicely scales when servicing from 1 to 250 highly demanding simultaneous users. On there own, these benchmarks are excellent. But they really standout, when we compare them to the other application servers in TechMetrix's study. When compared side-by-side, it is clear that WebObjects handily blows away the competition not just in performance, but also in scalability.

So, WebObjects scales well when running on a single machine. But how does it perform when you need to distribute your load over 10s or even 100s of systems? How easy is it to build a mission critical web application that can easily be distributed across multiple machines?

The short answer is quite easily. The long answer, is that WebObjects - like the restof the frameworks, including Cocoa, originally developed by NeXT - is based on a distributed objects (DO) layer. This layer allows you to easily take a WebObjects application and scale it from 1 to 2 to 10 to 100 servers, allowing you to grow your infrastructure to meet customer demand.

How many times have you found a web site or web application that intrigued you, but when you tried to use it didn't work or broke down at some critical point? And how quickly did you walk away from that web site? The lesson learned here is, it doesn't matter how feature packed and interesting, or fast your web application is, or how well it scales, if it doesn't run smoothly and reliably, customers will dump you and go somewhere else in a New York minute.

Once again, WebObjects delivers the goods. Unlike half of the application servers that TechMetrix studied, WebObjects successfully performed under all workloads. This coupled with it excellent performance and scalability clearly show that WebObjects is able to deliver the goods under all conditions.

Performance, scalability, and reliability are basic "hygiene". Without them, you don't have a chance of competing, but they don't make for a compelling tool.

So, how does WebObjects move beyond hygiene? Based on the same object-oriented foundations as OpenStep and Cocoa, WebObjects, is a highly productive development environment. If you are impressed by the developer productivity delivered by OpenStep or Cocoa, you already know the developer productivity delivered by WebObjects. If you don't then you owe it to yourself to experience it.

WebObjects also includes a powerful collection of classes, Enterprise Objects Framework (EOF), that gives WebObjects' applications easy access to new and legacy databases. For example, the EOF features of WebObjects allowed the IS folks in the office of the Secretary of Defense to build an application that tied together numerous legacy systems - many running on older mainframes - into a single application with a clean and unified user interface. When building its Personal Wealth application, Standard & Poors ran into similar issues when trying to interface with existing databases from various vendors. Again, EOF allowed Standard & Poors to build a single application that presented a clean and unified human interface to users. In fact, much of the power of WebObjects comes from EOF. Without it, WebObjects would not be as powerful a tool as it is.

Given what you have learned about WebObjects, you are probably asking yourself, "If it is so good, what isn't everyone using it?"

The answer in part, is Apple doesn't advertise WebObjects. But if we think that Apple should advertise WebObjects, we have to ask ourselves, what would be the impact? How would an ad for WebObjects from Apple be received by the average reader of The Industry Standard or PC Week? Probably with a high degree of skepticism. Given Apple's track record in the enterprise, it probably doesn't make a lot of sense for Apple to throw dollars into advertising for WebObjects. Rather, they need to focus on making sure that the decision-makers considering a project know about WebObjects and its power.

So, how do we get WebObjects in front of decision-makers with creditability? First, we need to have powerful success stories to which we can point. With over 3,000 mission critical applications already built using WebObjects from many high profile companies, Apple has a rich field of candidates for success stories. And Apple has done an excellent job of collecting WebObjects success stories from this field. If you are interested you can find them at Apple's WebObjects web site (see Links of Interest below for the URL).

WebObjects, like other application servers, is going to be sold one-on-one. Be it by Apple sales reps or Apple partners, the sales of WebObjects will happen in one on one settings. It is when someone, armed with the success stories that Apple is producing, can talk to someone looking to build a web application, that the sales of WebObjects will happen. Advertising won't drive it in any meaningful way. So, maybe Apple's stealth marketing makes sense. If advertising isn't going to drive sales, why waste the money? Maybe Apple isn't as dense as many of us thought!

If reading about the power and advantages of WebObjects above has you interested in learning more, there are a lot of resources available to you.

First and foremost, you can start off by reading Sam Krishna and Patrick Taylor's first article in their series on developing with WebObjects, "Everyone meet WebObjects. WebObjects meet everyone." starting on page <EDITOR PLEASE ENTER> in this issue. If you are serious about learning more about or using WebObjects, make sure you read their entire series as it unfolds over the course of the next year.

Surprisingly enough, Apple has a large amount of material available for you on their web site. If you are looking to explore things from top to bottom, then check out the Apple WebObjects home page (see Links of Interest below for the URL). If you are looking for a balanced, third-party perspective on WebObjects check out the IDC WebObjects White Paper posted on Apple's web site (see Links Mentioned below for the URL).
